The hip-hop world is in mourning after Floyd Sullivan, stepfather of Rae Sremmurd‘s Swae Lee and Slim Jxmmi, was reportedly murdered on January 6. Law enforcement sources told TMZ that the TK-year-old, who raised the twins, 28, since they were in middle school, was fatally shot at home in their hometown of Tupelo, Mississippi, and their 19-year-old half-brother, Michael Sullivan, is apparently the prime suspect.
